* dcrt0.cc: Semi-revert commit 12743c2d5d2721f3a80b4d7671a349be03c1f520.
(dll_crt0_0): Drop setting wow64_needs_stack_adjustment on 64 bit.
(_dll_crt0): Split out 64 bit code again and always create new main
thread stack, unless forked off from the non main thread in the parent.
Call create_new_main_thread_stack with parent stack commitsize if
started from the parent's main thread.
Only call child_info_fork::alloc_stack for the latter case on 64 bit.
Slightly rearrange moving rsp and rbp to new stack and document how.
Revert 32 bit wow64 handling to its former self.
* miscfunc.cc (create_new_main_thread_stack): Take a commitsize
parameter and use it if it's not 0. Don't set _main_tls here, it's
done in the caller _dll_crt0 anyway. Return stackbase - 16 bytes,
rather than stacklimit (which was very wrong anyway).
* miscfuncs.h (create_new_main_thread_stack): Accommodate declaration
to aforementioned change.
* wincap.h (wincaps::has_3264_stack_broken): Remove element.
* wincap.cc: Ditto, throughout.
* wow64.cc: Semi-revert to pre-12743c2d5d2721f3a80b4d7671a349be03c1f520
but keep architecture-agnostic type changes intact. Fix formatting.
* wow64.h: Revert to pre-12743c2d5d2721f3a80b4d7671a349be03c1f520.
